Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during the repair.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the front or rear wheels, depending on which brakes are making noise.

3. Inspect and Replace Brake Pads

Remove the brake caliper by loosening the caliper bolts using a socket set.
- Tools: Socket set, torque wrench
Carefully hang the caliper using a bungee cord or a caliper hook to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of damage or fluid leaks.
Apply brake grease to the back of the new brake pads to reduce noise.
Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are damaged, remove them by loosening the rotor retaining screws (if applicable).
Install new rotors, ensuring they are clean and free of oil or debris.
Torque the rotor screws to manufacturer specifications.

5. Reassemble Braking System

Reattach the caliper over the new brake pads and torque the caliper bolts to the specified torque (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (typically 80-100 ft-lbs).

6. Final Checks

Reconnect the battery.
Check the brake fluid level and top off if necessary.
Pump the brake pedal to ensure proper brake pad seating.
